It's not N-factorial; where did you come up with that?  It's
N-squared.

No.  When you send mail to your contacts, you'll need to use their
public challenge-response address to revalidate yourself.

This is a pain, no doubt.  There's no pain-free way to end spam that I
can see.

No, not really.  Like I said, you have an initial challenge-response
contact address for the first contact.  You need to make the challenge
easy to solve by a human, but hard for an automated process.
